PHILANDER F. CHASE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHASE ELEVATORCOMPANY, OF SAME PLACE.

GRAIN TRANSFERRING AND WEIGHING ELEVATOR APPARATUS.

EPECIFICATION forming part of Letters Patent No. 383,860, dated June 5,1888,

Application filed August 29, 1887. Serial No. 248,168. (No model.)

To all whom it may concern.-

Be it known that I, PHILANDER F. CHASE, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois,haveinvented a new and useful Improvement in Grain Transferring and WeighingElevator Apparatus, of which the following is a specification.

This invention relates to apparatus for trans ferring car-loads of grainfrom one car to another and Weighing the car-load as it is transferredin hopper-scales.

The invention consists, in connection with the loading and unloadingtracks,of a transferelevator building located between the tracks andprovided with one or more weigh-hoppers located in the building on abouta level with the cars, a receiving-elevator for elevating the grain intoa car-load bin above the weighhopper,and a second or shipping elevatorfor-elevating the grain discharged from the weighhopper, from which lastelevator the grain is spouted or delivered through a self-trimminggrain-spout into the car.

The invention also consists in the novel devicesand novel combinationsof devices herein shown and described, and more particularly pointed outin the claims.

In my invention the shipping-elevator delivers the grain directly intothe self'trimrning loading-spout and projects the grain forciblydownward into the spout with a velocity equal to or approximating thatof the grain in the elevator,or thatof the elevatorbuckets and belt,thus obviating the necessity of employing a self-trimming spout of theusualgreat length in order by the fall of the grain therein to give itthe requisite velocity to properly spout the grain through the curvedbranches of the spout t0 the extreme ends of the car. As the ordinaryvelocity of a belt-and -bucket elevator is in practice generally aboutfive hundred and fifty feet per minute, and necessarily so, in order tocause the grain to properly discharge from the buckets by thecentrifugal action as the belt passes around the upper pulley, it willbe seen that by means of this same shipping-elevator the grain alreadyhas a high initial velocity when it enters the mouth of theself-tri1nming loading-spout. By this means I am enabled to employ aself-trimming loading-spout of thirty feet or less in length, and tocorrespondingly diminish the height of the building and the height towhich it is necessary to elevate every ton of grain. This diminishedheight of the elevator frame or building is a matter of very greatconsequence in the practical construction and operation of graintransferring and weighing apparatus de signed for transferring eachidentical car-load of grain from one car to another, for the reason thatit is desirable that the elevator building or frame should be made asnarrow as possible and not take up any more of the valuable and limitedtrack-space than can be helped.

By means of my invention the elevatorbuilding need not be made more thanforty feet high and not wider than twenty feet, thus taking up the spaceof only two tracks. WVhere the elevator transferring and weighingapparatus are so combined together, as heretofore, that the buildingmust be made of great height in order to properly operate theself-trimming loading-spouts,the building is necessarily madecomparatively wide in order that it may have the requisite stability,thus rendering it usuallyimpracticable to locate such elevatortransferri ng and weighing apparatus in the railroad track-yards, whereit is desirable that the apparatus should be located for convenience intransferring from the cars of one road to those of another; and wherethe elevator-building is constructed with the railway-tracks runningthrough thebuilding the difficulty is not diminished, because suchtracks cannot be used for any other than elevator pnrposes,as thelocomotives are never permitted to run through such buildings on accountof danger of fire and in surance regulations.

By my invention the elevatonbuilding is made low and narrow, thusgreatly diminishing the cost of construction, the height of theelevating, and the consequent cost of operat ing or driving themachinery, and at the same time, as the tracks are located on each sideof the building, the locomotive can pass freely over the same, so thatthe tracks are not ob- I structed for other or general use, and thusalso greatly increasing the facility with which 1 the cars may behandled in respect to the elevator-building.

By my invention also, as the scales and weigh-hoppers are located on thefirst floor of the building or on about a level with the cars from whichand into which the grain is unloaded and loaded, instead of in theneighborhood of one hundred and fifty feet above the ground, asheretofore has been the case where self-trimming loading-spouts havebeen employed, the weigh-master, being thus on a level with the cars,can readily see the car from which the load is taken, and also the carinto which it is delivered after being weighed, and thus himself notetheirinitials, numbers,

and other data, and thereby avoid customary mistakes.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is a transverse sectional view of a device embodying my invention. Fig.2 is a longitudinal sectional view, partly in section. Fig. 3 is a planview showing the weigh-hoppers, and Fig. 4 is a similar view indicatingthe car-load bins from which the grain. is

spouted into the weigh-hoppers.

In said drawings, A represents an elevator building or frame-work,preferably about twenty feet in width and about forty feet in height.The lengthof the building may be varied as it is desired to load orunload one, two, or more cars at a time, and to employ one, two, or moreweigh-hoppers. The apparatus is preferably constructed of such size thatit may be provided with four separate hopperscales and eight car-loadbins above the same.

B B are, respectively, the unloading and loading railway-tracks on eachside of the elevator-building A, upon which the cars to be unloaded andloaded and their loads weighed are run.

0 represents the receiving-elevator, consisting, preferably, of theordinary belt and buckets, into the boot 0 of which the grain from theear. D is unloaded by the steam-shovel unloading apparatus E. The chuteF delivers the grain into the boot of the elevator.

The steamshovel unloading apparatus E is or may be of the usualconstruction, which is well known and need not be here described.

G isthe weigh-hopper ofthe scales G. These scales are of an ordinary andwell-known construction. The weigh-hopper is arranged or located in thelower story of the building A. Above the weigh-hopper G are two car-loadbins, H H, each adapted to hold a car-load of grain and each providedwith gates it, through which the contents of the bin may be deliveredinto the weigh-hopper. The grain is delivered from thereceiving-elevator G into one or the other of the bins H by the swingingor reversible spout c, which is adapted to swing from one bin H to theother. The grain is discharged from the weigh-hopper G through a spout,g, into the boot of the shipping-elevator K, the weigh-hopper G beingfurnished with a valve, g, for closing the same. By theshipping-elevator K the grain 1s again elevated, preferably to theheightof about thirty feet, and delivered into the self trimming grainloading spout N through the curved or horn'shaped branches n, by whichthe grain is spouted automatically to the ends of the car, so as torequire no shoveling inside the car.

The elevator K gives the grain such an elevation as will by its fallthrough the spout N and its curved branches n spout the grain to theopposite ends of the car.

In operation the car D is run upon the track B opposite one of thereceivingelevators C. The grain is shoveled from the car by thesteamshovel E and delivered into the receiving-elevator O, by which itis elevated and spouted into the car-load bins H. Thence it is spoutedinto the weigh-hopper G and weighed by the scales G. The gate of theweigh-hopper is then opened and the grain discharged from theweigh-hopper into the boot of the shippingelevator K, by which it isagain elevated and delivered into the selfloading spout N, from whenceit is spouted directly into the car M to be loaded. The two car-loadbins H, each of which is adapted to receive a car-load of grain anddeliver it into the weigh-hopper, enable the operations of unloading andloading to be carried on both about continuously as well as weigh-hopperand one load in each of the carload bins, without the operation ofunloading being arrested to await the switching 1nto place of the carsto be loaded. And so in like manner the operation of loading may becarried on practically continuously as fast as the cars to be loaded arebrought into place.

As illustrated in the drawings, four separate weigh-hoppers arepreferably employed and eight,'or four pairs, of car-load binstwo foreach weigh-hopper. It will be observed that the weigh-hoppers G andscales G are on the first floor and preferably on about a level with thecars, so as to be conveniently accessible.

By my apparatus grain may be rapidly and quickly transferred from onecar to another and weighed without any hand-shoveling of the grain, allthe different steps being performed-by the conjoint operation of theseveral parts of the apparatus.
